Abstract: The vehicle that includes a primary chassis supported by a road; a secondary chassis adapted for supporting the driver and movably linked to the primary chassis; the secondary chassis being out of a mechanical contact to the road; and at least one mechanism adapted for controlling movement of the vehicle. The mechanism non-resiliently reacts to changing positions of the secondary chassis and the driver's body such that the driver is able to maintain resultant vector of forces applied to the secondary chassis directed to a point of a linkage between the primary chassis and the secondary chassis.

Abstract: A vehicle controlled by a driver comprises a primary chassis (22) supported by a road, a secondary chassis (16) movably linked to the primary chassis and at least one mechanism adapted for controlling movement of the vehicle. The controlling mechanism is adapted to change characteristics of vehicle movement and vehicle configuration according to a position of a body of the driver relative to the vehicle and a relative position of the primary (22) and secondary (16) chassis.
